Thunderstorm early warning system and method

Abstract

The invention relates to the technical field of power grids, particularly relates to a thunderstorm early warning system and method. The system comprises a thunderstorm short-term and temporary forecasting module, a thunderstorm potential forecasting module, a thunderstorm real-time monitoring module, a user management module and a thunderstorm forecasting and early warning visualization module. Refined forecasting product data are provided based on short-term and temporary forecasting and potential forecasting of power grid thunderstorm forecasting data, and are accessed to a deployed serverthrough an API (Application Program Interface) to transmit a forecasting result in real time, and the forecasting result is displayed through a forecasting and early warning visualization system platform based on a Web GIS (Geographic Information System) technology. The thunderstorm forecasting and early warning project system can be divided into a data source layer, an original data layer, a datastorage layer, a calculation layer and an application service layer as a whole. According to the method, the influence of lightning activity on the power transmission line can be effectively discovered in advance, the scheduling and emergency plan making management level is improved, a good foundation is laid for safe, stable, high-quality and economic operation of a power grid, and the safety and benefit society is remarkable.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a thunderstorm early warning system and method. Background technique [0002] Due to its physical effects such as strong current, scorching high temperature, strong electromagnetic radiation and violent high-voltage shock wave, lightning can produce huge destructive effects in an instant, causing lightning disasters. Lightning has always been one of the most frequent natural disasters in the power grid. Lightning generally causes flashover and tripping of the line, and may also cause permanent faults such as insulator falling off and wire disconnection. Thunder and lightning activities are mainly concentrated in spring and summer, and show certain periodic characteristics as the year changes. Among the various regions, South China is most severely affected by lightning, especially the important ultra-high voltage transmission channels. Therefore, the impact of lightning on p...

AI Technical Summary

Problems solved by technology

The lightning potential forecast provided by the meteorological department at this stage cannot meet the needs of lightning damage prevention and control for transmission channels in terms of temporal and spatial resolution and accuracy. It is necessary to build a refined meteorological risk analysis and lightning early warning system for transmission lines.
